Hi guys
I have a Arduino UNO, Bluetooth shield and relay shield, all working as it should.
My only concern is security, as I plan to use this for controlling a warehouse door.
At the moment I am sending a single character over bt serial to control a relay.
How would I go about this secure, is it enough to just change the pass key of the bt shield?
Thanks.
Why don't you send a sixteen character command to control the relay?
Is it that simple? If so happy days.
Many thanks.
I think it should be. You just have a string "bnghyjusthaveast" which is in Arduino and has to be checked. I understand you cannot retrieve a programme from Arduino, so I guess the code is safe even if the device is stolen.
